This post is a gift to my future self for when I no longer writer Python daily and need a refresher.

Chris Yeh has a wonderful post on the correct syntax to write import statements in Python.

The essence is, if you have a directory structure like:

awesome_project/
    run.py
    foo/
        __init__.py
        bar.py
        baz.py

In run.py:

from foo import bar

bar.Bar()

In baz.py:

from .bar import Bar

Bar()
